I've built an automation framework in VS and have roughly 25 Unit Tests. These files have been showing and running fine for about a year now. However, a few days ago, all of the tests have stopped showing in the Test Explorer. The five .ordertest that I have in the project show just fine, they even run the Unit Tests that aren't showing when I run them. I have tried cleaning the build, rebuilding, closing / opening, pulling an older version from my repository, switching architecture in the test panel, etc.
At this point I'm at a loss and really need some help. Thanks!
